PATENT f opFFlcE LOUIS CHARLES DUPUIS, OF NEW BEDFORD, MASSACHUSETTS HIGH SPEED SPINDLE Loox Application led August 6,

This invention relates to that type of high speed spindle employed in skein spoolers, spoolers, twister-frames as well as spinning frames; and the main object of the present invention is to provide simple means for thoroughly oiling the spindle and at the same time safely hold the spindle in its supporting socket, as more fully hereinafter set forth.

Referring to the drawings annexed Figure 1 is a side elevation of my improved spindle;

` Figure of;

Figure 3 is a detail side elevation of the bushing removed, and

' Figure 4 is a horizontal section on the line 4-4 of Figure 2.

Referring to the drawings annexed by reference characters, 5 designates the usual supporting-tube having a closed bottom andan open top and also provided near its top with a horizontally-projeating tube 6 Whose outer end is turned upwardly to form an oiling nipple 7 normally closed by a ball valve 8, the inner end of the tube 6 being in communication with the interior of the supporting tube 5.

Fitting loosely down in the supporting tube is a bushing 9, which is held non-rotatably therein by means of a rib 10 formed on its exterior near its upper end and is adapted to have a sliding it in a corresponding groove formed in the supporting tube. This bushing is provided with an annular groove 11 near its lower end, one or more holes 12 near its lower end at a point above the groove 11, and at a point in line with the tube 6 with a hole 13.

Stepped in and nicely itting the non-rotatable bushing 9 is the lower pintle-end 14 of the spindle proper which at its upper end carries the usual pulley 15 which fits down loosely around the upper end of the supporting tube 5. This pintle 14 is provided with an annular groove 16 in line with the hole 13 in the bushing. Extending through the hole 13 and into the groove 16 is the inner end of a screw 17, which is hollow throughout most of its length and is provided near its outer end with holes 18 to receive the oil that is 2 is a vertical sectional View there- 1930.

poured into theitube 6 through the ballvalve 8. It will be seen that when oil is fed in through the nipple 7, it will enter the `holes 18 and be delivered into the groove 16 and thence will move upwardly aswell as downwardly around the pintle and in that manner keep the pintle thoroughly lubricated. In this way also the pintle will be held against removal upwardly out of the bushin 9, but it will be readily removablefrom t e bushing by unscrewing the screw 17 far enough to take its inner end out of the groove 16. It will be observed that oil will run from'the tube 6 into the space around the bushing 9 and will work downwardly"4 around the bushing a-ndenter the holes 12 and thus assist in lubricating the lower end ofthe pintle. Any oil that works around the pintle up over'the upper end of the bushing 9 will run down on the exterior of the 7 bushing .and thus be prevented from flowing out over the top end ofthe supporting tube 5. In the manner above set forth it will be seen that the pintle 14 will be thoroughly lubricated at all times and also that the hollow oil supplying screw will serve to lock the bushing and pintle in proper position in the supporting tube. The rib 10 serves to position the bushing in the supporting socket in such manner that the hole 13 will always register with the end of the screw. The screw 17 is tapped through the outer end of the tube 6 and may, therefore, be readily ad- Justed inwardly or outwardly by merely turning the screw by means of a screw-driver.

I claim:

1. In a spindle structure of the class described, a supporting tube, a non-rotating bushing supported therein having a hole formed in it, a spindle having a depending pintle rotatively supported in said bushing and having an annular groove opposite said hole, an oil supplying tube attached to the supporting tube and extending laterally therefrom and provided with an oiling nip-` ple, and a hollow screw tapped through the end of said oil supplying tuber and having its inner open end extending through the hole in the bushing and into the annular groove in the pintle. v

2. A spindle structure of the class described, a supporting tube having a. lateral oil-tube provided at its outer end with an upturned valved oiling nipple, a bushing in 5 said supporting tube and having a loose fit therein and provided with an oil hole at its lower end and also with another hole above saidoilhole, .saidbushing having a. free fit in said supporting tube, and a spindle having 10 a, driving pulley surrounding the upper end of the supporting "tu-be and alsozr pintle depending into the bushing, thspintle. being provided With an annular groove coincident With the upper hole in the bushing, anda hollow screw tapped through'the outer end of the'vzmlvedoil-tube and having itsfzinner 'end entending'into lfsaidfgroove 'through ythe iholeinzthe bushing.
